Embodiment Construction

[0044] Figure 1a and Figure 1b A reactor 10 according to a preferred embodiment of the present invention is shown relatively schematically. The reactor 10 in Figure 1 comprises a straight cylindrical flow tube 12 inside the reactor 10 at a distance from the inner surface of the wall of the reactor, preferably at least one electrically conductive electrode substantially in the center of the flow tube The rod 16 is fastened by means of an arm 14, in this embodiment the rod is electrically connected via an arm 14' to a control system 18, preferably comprising a voltage source. Where the flow tube 12 is made of metal, as it is in most cases, the electrode rod 16 must be electrically isolated from the flow tube 12 . This is performed, for example, by arranging the fastening arm 14 and the fastening arm 14' of the rod 16 to consist of a non-conductive material, or by making the rod 16 mainly from a non-conductive material and coating a suitable portion of the rod with a conductiv...

Abstract

The present invention relates to a method and a reactor for mixing one or more flows into a process liquid flow. Advantageously the method and reactor according to the invention are suitable for introducing such flows into a process liquid flow that either alone or together with a process flow tend to form organic or inorganic deposits onto the wall of the flow pipe. Especially preferably the invention is suitable for use when the chemicals of papermaking are introduced into the pulp.

Description

technical field [0001] The present invention relates to a method and reactor for mixing one or more chemicals into a process liquid stream. Preferably, the methods and reactors according to the present invention are adapted to introduce and mix into process liquid streams one or more chemicals which, alone or together with materials entrained in one or more process streams, tend to Formation of organic or inorganic layers, buildup or deposits on the walls of the flow tube. The invention is especially preferably suitable for use when one or more chemicals for the production of paper and pulp are introduced into the production process, eg in the wood treatment industry. Background technique [0002] For example, in papermaking, as in many other areas of industry, there is a need for introducing and in-line mixing at least one such substance (hereinafter referred to as a chemical in the broadest sense of the word) into a flow tube by itself. in, or they may form accumulations...
